Fig. 2.
Meta-analysis of prevalence of AKI and CRRT as well as two laboratory indexes of kidney injury. Forest plots represent the comparisons of the prevalence of AKI and CRRT and standard mean differences (SMD) in two laboratory indicators between non-survival and survival cases. A, sCr (serum creatinine, μmol/L); B, BUN (blood urea nitrogen, mmol/L); C, AKI (acute kidney injury); D, CRRT (continuous renal replacement therapy).
